If we accept this kind of shit, there will soon be hundreds of leeches asking for their share of our money. And then even the most wealthy developers will feel the pain. I say squash those bugs early. If Apple, Google, and MS pay, they are stupid.
What was written as fiction, is actually happening in real life. We've made defending against frivolous patent claims expensive enough that someone with a broad enough patent can nickel and dime a large enough group of people hoping many of them will say "0.575%? Fuck it, I'll just pay..."
It will be interesting to see how this pans out in the long run...
